Arrow Down



When you’re buying or selling a home, we understand there are a number of hoops you need to get through before that final closing day. If you are planning to sell or buy a house that has a private well protect yourself by testing your drinking water. Not sure what's required? See what tests you'll need depending on your loan type.

Municipal Testing

TCWC is certified by The Minnesota Department of Health to complete water testing for municipals. With over 50 years experience in testing for cities, you can feel secure knowing the continuous health of your cities' drinking water. Don’t have time to drop the water samples off at our lab? We’ll come to you!  


If you're drilling a new well the state of MN requires Bacteria, Arsenic, and Nitrate testing done and highly recommends testing if repairing an existing well. TCWC has plenty of experience testing new and existing wells, we test 25% of all new wells put in Minnesota each year!


As a school administrator you have an abundance of items on your list - we’ll make lead testing easy for you to check off.  TCWC is certified to test drinking water for heavy metals, including lead, so you can be confident in what your kids and staff are drinking. We not only analyze the tests, but also able to work with the school districts to organize and collect the water samples too!


Regardless the size of the construction project, you need to be confident that new or temporary water lines are delivering clean water. This requires a Bacteria Coliform test.

We understand that the term “ASAP” doesn’t quite cover how quickly results are needed. From the final sample taken, get a full report in 1-2 business days! Don’t have time to send someone out to our office? We’ll come to you and take the sample so your crew can continue on with their day.
